Not so much a kink for me as a passing musing (such is the nature of my asexuality), but thoughts on slime tf or just being generally amorphous? Sometimes I feel like it'd be very relaxing to just melt into a puddle or nap in a bucket, giving up any pretense of expending effort on keeping a form.
yeah this is also just absolutely a cozy one, my form is malleable enough anyway that reshaping on the fly (or collapsing down) can be comfy thoughts
